High Pressure Switch
The High Pressure Switch is a safety-critical limit that opens the electrical circuit if the system's discharge pressure exceeds a specific threshold. On the RA20 inverter system, the control board performs a continuity check during the soft-start sequence; if the switch is electrically faulty or detects a pressure excursion, it triggers a hard stop to prevent compressor scroll damage. This cycle typically repeats as the system attempts to re-initiate the startup protocol after a temporary lockout period.
